Letters Patent No. 84,054, dated November 17, 1868.
IIWPROVEMENT IN STEAM-ENGINE SLIDE-VALVES.
"'-Hbom- The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may conce/rny Beit known that we, JOHN S. Evnnrrr and Ossmn 000K, of the city of Oshkosh, county of Winnebago, and State of Wisconsin, have invented a new and improvedBalance-Slide Valve for Steam-Engines, with an attachment for reversing motion and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same,`reference heilig had to the annexed drawings, making a part of this specification, in which- Figure l is a horizontal sectionof steam-chest andvalve.
Figure 2 is a vertic the dotted line 3 3, pipe attached.
Figure 3 is a verti the dotted line 2 2 Figure e is a vertical longitudinal sec through dotted line i 4, iig. 2.
Figure 5 is a vertical cross-section, cutting through dotted line 6 (i, of valve H, fig. l.
Figure ii is a vertical cross-sectie dotted line 7, of valve H, iig. l.
Figure 'Z isa cross-section ofreversiu through dotted line 5 5, iig. 2. also as a throttle-valve.
H, in fig. l, is a horizontal section of balance-valve.
A A is the shell ofthe steam-chest or valve-case.
B B are steam-*chest heads.
O is the valve-stein.

S S 'are valves, jnstably connec in iig. l.
n n are cams, attached by set-screws to and slide on the valve-stem C, a's seen in iig. 6, and serve to adjust the valves, pressing thein out as they become worn, and thus keep the v-alve well fitted to its seat.
I I are injection and eiection-pipes, connecting the sin g-valve F with the balance or main al crosesection, cutting through iig. l, with reversing-valve and cal cross-section, cutting through tion, cutting i n, cutting' through gvalve cutting rlhis valve operates steam-ports. 1s a combined throttle and reversbridge in the bottom of valvehat serves to secure the valve tion, and contines it strictly to a and ejectiorbpassages. arms, secured to the valve-stem iC, seen in iig. 2.
with lugs fr fr, by which S S are adted to arms m m, with bolts, as seen valve H.
K is a supply, and K is an exhaust-pipe. Our invention consi sts in the construction of a slidevalve, that is hollow, and with holes, in a known form, on the outside, the one opposite the other, so that the pressureon either side balances that ofthe other, the same to be constructed separately, the one from the connected to the valve-stem, so orn they maybe adjusted through ade to till the valve-chest, and lit seat, thus compensating for wear.
that as they become w suitable cams, and In Our invention further consists in the arrangement of the hollow balance-slide. valve, and the reverse and throttlewalves, when provided with a steam-chest, having suitable steam-ports, injection and ejection-pipes and passages, and supply and exhaust-connections, and the whole so constructed that the motion of the engine may be reversed at will, brought at will to eithe valve. The valves cas metal, and the slide cylindrical or square.
`We will now proceed to describe its operation. With the valve H covering the ports E and D', (seen in lig. 1,) and the valve F adjusted as seen in iig. 7, the' steam will be received from the boiler into the pipe K, then passing through the pipe I, in the direction indicated by the arrow, to the insideof the valve H, and through the ports l) D cylinder ci" the steam-engine The exhaust steani'will be ejected from the cylinder, through the passage O', into the ports D il', the holes of the valve and the ports E E, the latter connected as seen in fig. 2, and thence through the pipe l haust-pipe K.
e and pipes are constructed of -valve and case may be either Adj ust the valve F, as indicated by the dotted lines` seen in fig. 7, and l becomes the induction-pipe, and I the eduction7pipe, and the induction and ednction of the steam will be reversed from that described, and the motion ofthe engine reversed-the steam will be received through the cuter holes of the valve, and Vwill be exhausted through the inside of the valve. In either case, it will be seen that the pressure or steam on the valve is uniform, whether it be from the inside or outside, and the valve is balanced.
Thev slide-valve may also be attached cylinder, and used as a double-.acting pump, without any other valve, in which case the water will pass through the valve exactly in the reverse direction from the courseof thesteam, when the valve is used as a steam-valve.
